 Hello fellow biofuelers,
 The following message was posted on another email list. I do not have
 this magazine yet. Sounds like this technology might be a god-send if
 the cost is tolerable. Maybe wrap these cells around IC engines, put
 them in solar collectors, etc? Sheesh, per the numbers given, one
 square meter of cells would generate 50 kW of electricity! Too good
 to be true???

 
 An article in the June issue of Popular Science told about some new
 technology about to hit the market. These are something like solar cells
in
 that they collect one form of energy and convert it into useable
electricity.

 But these are designed to absorb heat from another source and convert the
 heat into electricity. They are designing home heating furnaces that have
 these TPV cells lined around the internal combustion chamber to absorb the
 heat and convert it into enough electricity. A regular solar cell makes
one
 milliwatt per square centimeter. the TPV cell makes 5 watts of power per
 square centimeter. One model heating unit already on the market makes
enough
 power to run its own fan, recharge storage batteries, all the while
supplying
 enough heat for the house. The next generation units are predicted to
 generate enough electricity while heating the home to power the rest of
the
 house's needs and put juice back into the power grid during low energy
need
 times.

 If they can figure out how to do the same with airconditioning
 compressors(which also put out a lot of heat), dryers, and stove/ovens,
you
 Californians may not need any new power plants after all :0)

That will work well with fuel cells.

The article in Popular Science is actually rather short and does not 
provide much detail. It appears that TPV devices require a heat 
source with a temperature in the 800 to 1700 deg.C range. Here are a 
few web sites:

few fuel cells run at that temperature. none of the more popular ones. It's
also my understanding it's infrared light, not heat, that triggers these
babies.
